hitting/ biting

Gone • Nope

my son is one (15 months actually) but he's starting to slap and bite when he gets mad or frustrated and I'm not sure how to correct it. I've been told to paddle him but to be honest I think that will just make his hitting behavior worse.

and about the biting i've been told to bite back but he's one and I'm NOT comfortable with doing that.

HELP PLEASE!
